Specification of Letters Patent. Application filed June so, 1911. Serial No. 636,215.

Patented Nov. 14. 1911.-

To all whom it may concern:

Be it known that I, GILBERT W. .Goon- RIDGE, a citizen of the United States of America, and residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and Improved Shade-Holder, of which the following is a specification.

My invention relates to shade holders and,

particularly to improved meansfor mount- 1n such holders upon a lamp'socket or other suitable support, the object; of my invention being to provide an lmproved latching engagement between the holder elements serving to secure the holder to its support.

In the accompanying drawing, Figure'l is a vertical section through an illustrative embodiment of my invention in a shade holder mounted upon an electric lamp socket; Fig. 2 is a perspective of the spring ring shown in Fig. 1; and Figs. 3 and 4 are respectively a perspective and plan of the body of the shade holder, shown in Fig. 1.

The particular shade or globe supporting meanscarried by the holder 'form no part of my invention and I have shown by way of illustration, the usual set screws 5, threaded through the depending peripheral flange 6 of the holder. Any suitable globe supporting means may be substituted for those shown. 1

To lock the shade holder upon the supporting bead 7, her'eshown in its usual form at the lamp receiving end of an electric lamp socket 8, I provide a bead-engaging member which carries latching elements adapted to cooperate with corresponding latching elements on the body of the shade holder and snap into engagement therewith when brought into operative position by the rotation of said parts with relation to each other. In the form shown this bead-engaging member is formed as a spring ring 9 which may be slipped over the end of the socket in advance of theshade holder and snapped into position on the bead 7. .Depending lugs 10 extend downwardly from the lower edge ofthe ring 9 and outwardlyprojecting engaging oil'sets 11 are formed is provided with an inner flange 12 which so constricts the central aperture, that when the shade holder is 'pushed up over ring 9,

the latter is held: in contracted position and.

cannot escape the bead 7. The flange 12 is cut away at a number of points 13 corre- 'sponding to the number of lugs 10 on the ring 9, to permit the'ofl'sets 11 to pass beneath the flange. Upon the rotation of the shade holder with relation to the ring 9-, the ofl'sets 11 are brought under the flange 12 and support the latter. v

To prevent the accidental return-rotation of the shade holder and ring to such position that the oflsets 11 may escape through the cuts '13 in theflange, I provide rounded bumps M in .the slightly recessed portion 15 of the flange, which snap into the apertures 16 in the lugs '10- asthe shade holder is turned on the ring, by reason of the inherent resiliency of the lugs and are thus engaged by the latter. The shoulders 17 in the flange resulting from the formation of the slightly recessed portion 15 of theflange form abutments which properly position the lugs so that their apertures 16 fit over the bumps 14. After the Iugshave snapped .into this position it requires some eflort to turn the holder with relation to the ring 9 and the parts are thus securely held together and supported on the head 7 Various modifications embodying my invention will readily suggest themselves.

. Iclaim as my invention 1 A shade holder comprising a member adapted to be secured to a supporting bead apertured engaging tongues carried thereby, in combination with a shade-carrying mem ber recessedto receive said tongues and 6H- gage the latter on relative rotary displacement to prevent endwise separation of said parts, together with a projection entering the apertured tongue in such position to hold the parts against subsequent relative rotary displacement.

2.- In ashade holder, a shade-carrying member and an independent member adapted to be mounted upon a securing bead and engaging means for holding. said members together against either endwise or rotary motion" with relation to each other, saidthe. relative rotary displacement of said parts and having bumps adapted'to simultaneously tongues, substantially as described.

enter the apertures in said engaging 3. In ashade holder a spring ring adapted to be mounted upon a supporting ring '5 and provided with depending apertured lugs to be engaged by said engaging pro ections said'flange being recessed to permit the free passage of said engaging projections there- 5 through and having bumps adapted to enter the aperturesin said tongues upon the rotation of said parts with relation'to each other,

4 substantially as described.

' 1 4. A shade holder comprising a member 'adapted'to be mounted upon a supporting g bead and provided with depending tongues having engaging projections, in combination with a shade-carrying member with an internal flange beneath which the engaging projections on said depending lugs may be adjusted and means for holdingsaid parts against rotary displacement with relation to each other. y

In testimony whereof I have signed my name to this Specification, in the presence of two subscribing vwitnesses.
